The sum of x and y is 280. If x + 8 is y, when will the value of x be the same for both equations?
Answer:
x = 136, y = 144
Step-by-step explanation:
x+y = 280
y = x +8
use substitution
x + x+8 = 280
2x = 272
x = 136
y= 136+8 = 144
Answer:
the answer is x=136
Step-by-step explanation:
x + y = 280
x + 8 = y (substitute this expression for y)
x + (x + 8) = 280
2x + 8 = 280
2x = 272 -> x = 136
to find y:
x + 8 = y
136 + 8 = y
144 = y
CHECK:
136 + 144 = 280
yes

Step-by-step explanation:
Distributing the minus sign in the given expression results in ...
6x +1 -3x -(-1)
6x +1 -3 +1 . . . . simplify
The two expressions that show the constant terms as +1 - 1 are erroneous. The two constant terms are +1 -(-1) or +1 +1.
The correct expressions are the 2nd, 3rd, and 5th ones (b, c, e).

<2 and <4 are corresponding angles
m<4 = 17x° and m<2 = (9x+40)º
Find x and the measure of each angle.
Answer:
X = 5 u
m∠4 = 85º
m∠ = 85º
Step-by-step explanation:
17x = 9x + 40
17x-9x = 40
8x = 40
x = 40/8
x = 5
m∠4 = (17x)º = (17*5)º = 85º
m∠ = (9x+40)º = (9*5 + 40)º = (45 + 40)º = 85º
-29= x + 8
what is x
Answer:
x=-37 (the answer should have a negative sign.)Step-by-step explanation:
To solve this problem, isolate the value of x from one side of the equation.
First, switch sides.
-29=x+8
x+8=-29
Then, subtract by 8 from both sides.
x+8-8=-29-8
Solve.
-29-8=-37
x=-37
Therefore, the final answer is x=-37.

at time t, the position of a body moving along the s-axis is s=t^3 - 12t^2 + 36t m. Find the total distance traveled by the body from t=0 to t=3.
Answer:
27 m
Step-by-step explanation:
The position of a body is given by :
[tex]s=t^3 - 12t^2 + 36t[/tex]
We need to find the total distance traveled by the body from t=0 to t=3.
At t = 0,
[tex]s=0^3 - 12(0)^2 + 36(0)=0\ m[/tex]
At t = 3 s,
[tex]s=(3)^3 - 12(3)^2 + 36(3)\\\\=27\ m[/tex]
So, the total distance from t=0 to t=3 is equal to 27 m.

The number N of bacteria present in a culture at time t (in hours) obeys the equation N = 1000e^0.01t After how many hours will the population equal 1500? 2000?
Answer: N(t) = (2^t)*1500
Step-by-step explanation:
Let's define the hour "zero" as the initial population.
So if N(t) is the number of bacteria after t hours, then:
N(0) = 1500.
Now, we know that the population doubles every hour, so we will have that after one hour, at t = 1
N(1) = 2*1500 = 3000
after two hours, at t = 2.
N(2) = 2*(2*1500) = (2^2)*1500
After three hours, at t = 3
N(3) = 2*(2^2)*1500 = (2^3)*1500
So we already can see the pattern, the number of bacteria after t hours will be:
N(t) = (2^t)*1500

5y=15x+10
5y-15x=10
or
y-3x=2 .....(2)
Equations (1) and (2) shows that the lines are parallel. We know that for parallel lines, there is no solution.
An airplane takes off at a speed S of 226 mph at an angle of 18° with the horizontal. Resolve the vector S into components.
Velocity=226mph
Angle made with horizontal= 18°
The vector components would be [tex] 226~sin18° \hat{j} + 226~cos18° \hat{i} [/tex]
The vector components of Speed is [tex]\rm v_x[/tex] = 226 cos 18° and [tex]\rm v_y[/tex] = 226 sin 18°
What is a Vector ?
An parameter that has both magnitude and direction is called a vector.
It is given that
Speed S = 226 mph
Angle = 18 degree with the horizontal
The vector component are
[tex]\rm v_x , v_y[/tex]
here these are x and y components of the vector
V is the magnitude = |v| = 226
The vector component is given by
cos [tex]\rm \theta[/tex] = [tex]\rm v_x[/tex] / |v|
[tex]\rm v_x[/tex] = 226 cos 18°
[tex]\rm v_y[/tex] = 226 sin 18°
Therefore the vector components of Speed is [tex]\rm v_x[/tex] = 226 cos 18° and [tex]\rm v_y[/tex] = 226 sin 18°

What is the sum of 50.249 + 21.3
Answer:
71.549
Step-by-step explanation:
Answer:
The sum of 50.249 + 21.3 is 71.549.
Step-by-step explanation:
50.249 + 21.3 can be written as (50 + 20) + (0 + 1) + (0.2 + 0.3) + 0.049, which makes calculating the sum easier. 50 + 20 = 70, 0 + 1 = 1, 0.2 + 0.3 = 0.5, and you still have a 0.049. Add the numbers all together and you'll get that the sum of 50.249 and 21.3 is 70 + 1 + 0.5 + 0.049 or 71.549.
Simplify the expression. 9√3(8√3+9√5)
Answer:
B
Step-by-step explanation:
first of all we have to multiply 9√3 for each members in the brackets. For do this we have to multiply number x number and roots x roots
(9x8) = 72
(√3)^2 = 3
72 x 3 = 216
9 x 9 = 81
√3 x √5 = √15
81√15
now we have to added up the two results
